Embodiment Construction

[0066] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0067] An embodiment of the present invention provides a method for storage management, which is applied to a virtual machine system. A logical disk is assigned to a virtual machine of the virtual machine system, and the logical disk includes at least two types of physical disks; figure 1 shown, including:

[0068] 101: Obtain the composition information of the logical disk of the virtual machine, where the composition information of the l...

Abstract

The embodiment of the invention discloses a memory management method, a memory management device and a memory device. A virtual machine system is applied in the memory management method, and a logic disk is allocated for a virtual machine of the virtual machine system and comprises at least two types of physical disks. The memory management method comprises the steps of obtaining composing information of the logic disk of the virtual machine, wherein the composing information of the logic disk of the virtual machine is used for indentifying the distribution situation of memory space of the logic disk of the virtual machine in each type of physical disks; adjusting the composing information of the logic disk of the virtual machine by taking preset load equilibrium strategy. A new logic disk is not needed to be established by adopting the composing information of the logic disk of the virtual machine, so that mainframe migration is not needed to be conducted on the logic disk. Therefore, the time for solving the hot spot access problem can be shortened, and resources occupied by the hot spot access problem can be decreased.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a storage management method, a storage management device and a storage device. Background technique [0002] A virtual machine (Virtual Machine, VM) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. After the virtual machine is created, it will be allocated to independent storage space in the disk. [0003] The I / O (Input / Output, input / output) performance of the disk will directly affect the performance of the virtual machine. In the O&M process such as cloud management, due to business needs, it is necessary to adjust the I / O performance of business VMs in a timely manner. At the same time, once some physical disks have access hotspots, it is necessary to timely adjust I / O access to physical disks with lower loads for load balancing. Access hotspots usually exi...
